You say this is an EPIA, are you using the Unichrome driver?

If so, only the modelines built into the driver will work, and you must 
match those names.

It sounds like you are not using a modeline that has overscan. The 
driver should have a mode "720x480" with no overscan, which is what it 
sounds like you are using, and "720x480Over" that has "normal" 
overscan. If you are using a newer version of the driver, it will also 
have "720x480Noscale", which I use, that has only a little overscan, 
and turns the scaler off. There are also "640x480" and "640x480Over"

If you have the Unichrome source, the list of mode names are in 

Hope that helps.
